Echinacea plant named ‘Satin Nights’

ABSTRACT

A new and distinct  Echinacea  plant named ‘Satin Nights’ characterized by numerous medium size, rose purple inflorescences, a compact, dwarf habit, dark stems, and excellent vigor.

Botanical denomination: Echinacea purpurea.

Variety designation: ‘Satin Nights’.

The present invention relates to a new and distinct cultivar of Echinacea purpurea and given the cultivar name ‘Satin Nights’. Echinacea is in the family Asteraceae. This new cultivar originated from a planned breeding project for a dwarf plants using proprietary, unnamed Echinacea. Its exact parents are unknown. Echinacea ‘Satin Nights’ was selected for its dark stems and dwarf habit.

Compared to Echinacea ‘Emily Saul’, U.S. Plant Pat. No. 18,768, the new cultivar is shorter and has ray florets that are lighter and more perpendicular to the stem.

These characteristics in combination distinguish ‘Satin Nights’ as a new and distinct cultivar of Echinacea:

-   -   1. numerous, medium size, rose purple inflorescences,     -   2. compact, dwarf habit,     -   3. dark stems,     -   4. excellent vigor.

This new cultivar has been reproduced only by asexual propagation (division and tissue culture). Each of the progeny exhibits identical characteristics to the original plant. Asexual propagation by division and tissue culture using standard micropropagation techniques with terminal and lateral shoots, as done in Canby, Oreg., shows that the foregoing characteristics and distinctions come true to form and are established and transmitted through succeeding propagations. The present invention has not been evaluated under all possible environmental conditions. The phenotype may vary with variations in environment without a change in the genotype of the plant.

DETAILED PLANT DESCRIPTION

The following is a detailed description of the new Echinacea cultivar based on observations of 18-month-old specimens growing in the ground in the field in full sun in the trial bed under typical outdoor conditions in Canby, Oreg. The plants had been moved from one trial field to another the fall before. Canby is in Zone 8 on the USDA Hardiness map Temperatures range from a high of 95 degrees F. in August to an average of 32 degrees F. in January. Normal rainfall in Canby is 42.8 inches per year in the trial fields in Canby, Oreg. The color descriptions are all based on The Royal Horticultural Society Colour Chart, fifth edition.
